TextClusterLab: New AI framework for reliable text clustering evaluation
LLM-driven dataset generator lets you control class imbalance, compactness, and diversity
Evaluating text clustering algorithms is notoriously difficult because real-world textual datasets often suffer from ambiguous semantic boundaries, high-dimensional embeddings, and inconsistent cluster structures. Existing clustering dataset generators are built for numerical data, offering little support for text-specific benchmarking. This gap makes it hard to compare algorithms or reproduce results, hindering progress in applications like intent discovery, topic mining, and recommendation systems.
TextClusterLab addresses this by providing an end-to-end framework for text clustering studies. Its core is an LLM-driven dataset generator that can produce synthetic text datasets with controlled clustering attributes, including class imbalance, intra-cluster compactness, and inter-cluster diversity. Researchers can use these generated datasets as benchmarks to test algorithm robustness. The framework also introduces a verification benchmark to determine automatically whether a text dataset is suitable for clustering evaluation. By open-sourcing both the code and example datasets (13 pages, 4 figures, 9 tables), TextClusterLab aims to make text clustering research more reproducible and comprehensive.
